[0007] This method is advantageous when used for manufacturing kitchen worktops, etc. , the substrate is plywood or wood fiberboard, and the cover board is a thermosetting resin board that can be post-formed. Ru. Then, by heating the covering plate while the filling is not completely cured, The coated plate can be plastically reshaped. The above method is ideal for producing kitchen counter tops with water damming edges. It is. In order to assemble quickly and fill the void well, hardened fillings are Preferably, the space between the cover plate and the substrate is supplied under pressure.

[0008] 1, a, b, and c in FIG. 1 indicate the manufacturing stages of the plate material 1 according to the present invention. Conveyor device 5 0 supplies the substrate 2. The substrate 2 is made of wood, metal, or synthetic resin. has been completed. A bonding device 51 installed above the conveyor device 50 is connected to a storage device 5. 5 supplies the adhesive 19 to be applied to the substrate 2 by a roller 56; The substrate 2 is transported in the direction shown by the arrow 57. In the next stage (b in Figure 1) , the covering plate 3 is supplied from a storage holder 58 installed above the conveyor device 50. is attached to the substrate 2 coated with an adhesive 19. Covering plates 3 are synchronized with each other It is pulled out from the holder 58 by the rotating roller 52, and the roller 52 is sent out in the direction of the roller press 53, and the coating plate 3 is coated by this roller press 53. It is forcibly pressed against the upper surface of the substrate 2.

[0009] The cover plate 3 is made of foil, such as vinyl foil, synthetic resin sheet, plywood, or gold. Consists of genus plates. The cover plate 3 is installed so that its peripheral portion protrudes from the edge of the board 2. It will be done. The substrate 2 with the partially glued covering plate 3 is then turned over ( (indicated by an arrow 54), at a stop 34 provided at a certain distance from the mold 8. They are placed on the workbench 7 so as to be in contact with each other. The mold 8 is aligned with the desired border edge 5 shape. It has a matching shape. The substrate 2 is held firmly against the workbench 7 by the holding member 10. This holding member 10 is movable with respect to the workbench 7 and can be It can be fixed at a desired position with respect to the table 7. The outer surface of the peripheral part 4 is molded into mold 8. positioning means movable relative to the mold 8 in order to make sufficient contact at all points with the mold 8; 11 is arranged to press against the periphery 4 within the mold 8. Peripheral part 4 of covering plate 3 and substrate 2 The columnar space 12 surrounded by the edge 6 is filled with a hardening filler 13 (rear ) is filled. The filling 13 is supplied from a nozzle 38 of a filling supply device (not shown). Supplied. When the cavity 12 is completely filled with the filler 13, the supply is stopped; The filling 13 is cured. After that, the positioning means 11 and the holding means 10 are removed from the plate material 1. After moving to a resting position a certain distance away, the completed plate 1 is placed on the mold on the workbench 7. It is taken out from 8.

0010 FIG. 2 shows a plate material 1 according to the present invention, and this plate material 1 can be used as a top plate of a kitchen countertop, for example. It is used as This plate 1 has two border edges 5a, 5b. Figure 2 The border edge 5a on the left side of the center projects upward from the upper surface 14 of the plate 1. This way In this way, a water damming edge 15 is formed to prevent water from flowing down from the board 1 during use. will be accomplished. In this case, the substrate 2 is made of plywood or compressed wood fiber, and the cover plate 3 is made of secondary material. It is a sheet of thermosetting resin that can be shaped. The characteristic of this type of sheet is that the synthetic resin By heating the sheet until it is chemically sufficiently hardened, it becomes plastic again. The reason is that it can be reshaped. Therefore, the peripheral part 4 of the covering plate 3 is molded into the mold 8. The cover plate 3 is heated before it is placed against the cover plate.

[0011] FIG. 2 shows that a support plate 16 is placed on the substrate 2 to obtain the desired height of the border edge 5a. It shows that it is placed. In the vicinity of the border edge 5a, the edge 6 of the substrate 2 The shape roughly corresponds to the shape of the border edge 5a. As a result, the circumference of the covering plate 3 The expensive filling 13 filled in the columnar part 12a between the side part 4 and the edge 6 of the substrate 2 is very expensive. Only a small amount is required. Moreover, as shown by the two-dot chain line in FIG.

In the plate material 100 formed without providing the intermediate portion 12b shown in FIG. A minute portion 101 having a substantially triangular cross section is formed between the peripheral portion 4 of the covering plate 3 and the substrate 2 . Therefore, it is impossible to completely fill the area between the peripheral part 4 and the edge part 6 with the filling material 13. This is always difficult, and the minute portion 101 tends to become hollow. Furthermore, as shown in FIG. 12, generation of minute portions 101 as shown in FIG. 11 can be avoided. In order to achieve this, a cover plate 3 is bonded to a substrate 2 that does not have an edge 6 as shown in FIG. In the plate material 101, the volume between the end of the substrate 2 and the peripheral part 4 of the covering plate 3 is large. This results in a large amount of expensive filling material 13 being required. In this embodiment having the edge portion 6 and the intermediate portion 12b, such a problem will not occur. There isn't.

[0013] Furthermore, in this embodiment, the surface of the edge 6 has a bonding surface 18 with the covering plate 3 of the substrate 2. It merges with the boundary surface 17 that it crosses. With this, when the covering plate 3 is combined, Since the adhesive 19 is squeezed out from between the substrate 2 and the covering plate 3, the adhesive 19 is squeezed out from between the substrate 2 and the cover plate 3, so There is an advantage that there is no need to combine with 2 (see FIG. 3). However, Figure 4 As shown in FIG. Bonding is also possible when the bonding surface 18 is merged without having any. If the latter In this case, the amount of adhesive 19 squeezed out from between the plates 2 and 3 varies from place to place. If the bending line 20 of the cover plate 3 is different from the water, which may occur in practice, It should not be in a straight line in the vertical direction with respect to the plate material 1 that terminates at the damming edge 15. become. This can be avoided by the presence of a transverse boundary surface 17. A particularly suitable material for use as filler 13 is urethane resin. this substance is caused by a chemical reaction between two components that are mixed just before filling the cavity with material. Cures extremely quickly.

[0014] FIG. 5 shows a border edge 5 in which the cover plate 3 is placed on the side of the edge 6 of the substrate 2. It is bent back. Therefore, the border edge 5 has a finished outer appearance when viewed diagonally from below. have an opinion.

[0018] Finally, FIG. 7 shows a preferred example of an apparatus 33 for manufacturing the plate material 1 according to the present invention. In this case, the mold 8 is moved from its rest position 36 by a conveying means (not shown). It is possible to move from the substrate 2 toward the working position 37. And this base The plate 2 is integrally combined with a cover plate 3 made of a thermosetting resin that can be formed into a second form. The holding means 10 firmly holds the workbench 7 at the position where it abuts the stopper 34. and is held. This example includes heating means for heating the peripheral part 4. this After the peripheral part 4 has been heated to the desired temperature and reshaped, - the heating means 2 7 moves in the direction shown by arrow 28 - the peripheral part 4 is molded to a shape that matches the mold 8 and the finished product is The shaping process is completed. In this device, a substrate 2 to which a covering plate 3 is partially bonded is attached to the surrounding area. There is no need to move part 4 relative to mold 8 after heating it, which makes this method The advantage is that there is little risk of damage to the covering plate 3 during implementation. In this example, the positioning means 11 is a positioning tool that can be guided and moved relative to the mold 8. It consists of 59 pieces.

[0019] According to a preferred method, the hardening filler is fed under pressure into the cavity 12. Figure 8~ As shown in FIG. 10, a filling hole 60 is drilled in the substrate 2 in advance. heated After placing the substrate 2 with the covering plate 3 in the mold 8, a sealing plate 65 seals the cavity 12. is placed. The nozzle 61 of the injection head 62 is connected to the guide hole 60 . This injection The head 62 is, for example, a device for injecting a curable two-component substance under pressure. It makes up the department. In this way, the space 12 is filled with the hardening type filler under pressure. This not only ensures sufficient filling of the void, but also improves the adhesion of the peripheral portion 4 to the mold 8. is particularly good. The filling guide hole 60 may be provided in the sealing plate 65 instead of the substrate 3. good.

[0020] Note that if the shape of the border is modified, the sealing plate 65 becomes unnecessary. Shown in Figure 9 As shown in FIG. By pressing in the direction 71, the cavity 12 can be sealed. Also, As shown in FIG. 10, the edge 6 of the substrate 2 is chamfered to form an acute point 74. For example, by pressing the acute point 74 against the peripheral portion 4 in the direction of the arrow 75, the quality can be improved. Good sealing performance can be obtained.

[Effect of the idea]

As is clear from the above description, according to the present invention, at least one border In the plate material having a substrate and a covering plate that are coupled to each other, the covering plate has a The periphery of the cover plate and the edge of the substrate at the edge of the border are filled with a hardened filler. The substrate and the covering are placed above the area surrounding the raised columnar part and aligned with the edge of the substrate. An additional intermediate portion is provided between the cover plate and the additional intermediate portion is also hardened. It is filled with mold filler. Therefore, the filling material is injected in a liquid state into the columnar part including the middle part. As a result, it adheres to the entire boundary of the covering plate, and as a result, when the filling hardens, Therefore, no non-contact parts occur.

[0022] Therefore, according to the plate material according to the present invention, there is no need for the troublesome arrangement of filling pieces on the substrate. The process can be omitted and it is actually simpler. That's why and expensive edged hardwood Since no inserts are required, the finished board is somewhat cheaper. edge of board Filling can be advantageously saved by shaping the part to match the shape of the edging edge. can be done. This effect is due to the fact that the gap between the edge of the board and the periphery of the cover plate is small. Form the edge of the board so that it roughly corresponds to the shape of the edging edge. This is further enhanced by this. Furthermore, in the plate material according to the present invention, a substrate with a partially adhered covering plate is placed on a mold. Then, make sure that the outer surface of the peripheral part of the cover plate protruding from the substrate rests against the mold. Because it can be formed, this part of the cover plate can be easily bent into the desired shape, The above plate material can be manufactured using a simpler method without creating non-bonded parts of the cover plate. It has the effect of being able to be constructed.
